To @ZZ whom it may concern.-

e it known that i, EDWIN J. TOOF, a citizen of the United States, and aresident of New Haven, county of New Haven, and State of Connecticut,have invented new and useful Improvements in Rufiiing and ShirringAttachments for Sewing-lllachines, of which the following, taken inconnection with the drawings7 is a specification.

My invention relates to that class yof attachments for sewing-machinesusually provided with a blade rcciprocated by levers through the mediumof the needle-bar adapted to gather, ruffle, and shirr; and it consistsin the means for adjusting the throw of the blade, acting in conjunctionwith the said levers, in a manner as will hereinafter be set forth indetail, and pointed out in the claims. Referring to the drawings,Figures l and 2 represent the two sides of my improved ruiner, and Fig.3 represents a top view of the same. Fig. 4 represents the end of therutlier opposite that which connects with the presser-bar Fig. 5represents a sectional view of the rufiier-frame, levers, and blade withthe separator-plate detached.

To enable others skilled in the art to more fully understand theconstruction and Operation of my improved ruiiier, I will eXplain morein detail.

In the drawings, the part indicated at A represents that part of theframe of the attachment intended to connect with the presserbar of asewing-machine, the upper part of which is provided with a recessforming a part of a circle, (see Fig. 3,) at the mouth of which islocated a screw, which, in conjunction with the horn formed by thecurved part of the frame, serves, in conjunction with the slipper partof the frame, to receive the toe part of the presser-foot to securelyfasten the attachment in position for operation. The slipper partreferred to forms a socket for the toe part of the presser-foot and isformed by an upper part and a lower sole, (indicated at B and B,rcspectively,) which parts are secured to the one side of the frameproper in position to embrace the toe of the presserfoot when placed inposition for operation.

C is a horizontally-arranged lever pivoted to an upright forming a partof the frame proper, one end of which is adapted to embrace theneedle-screw of the needle-bar of a sewing-machine and the opposite orfree end is bifurcated at its lower cdgeforming two horns or curvedarms, and D represents a `vertical lever pivoted to the same projectionand at the same point with the bifurcated lever C. It is also pivotallyconnected with a horizontally-arranged bar forming a guide (shown at F)for directingthe gatheringblade I, which is connected thereto. The saidbar or guide in the particular instance is slotted and is held andguided in proper position by a rivet or screw the head of which is moreclearly shown in Fig. l of the drawings at a. To this vertical lever issecured a cam (indicated at G) adapted to act vertically thereon, and isheld in position upon said lever by a screw, rivet, or other suitablemeans within a head, the diameter of which is larger than the slot withwhich the cam is provided, and by an adjusting screw or nut (shown at E)connecting with the upper part of said cam, which screw 01 nut issupported by an overhanging ear eX- tending from the upper part of thesaid lever, substantially as shown in the drawings at D.

The attachment is also provided with a separator-plate hinged to themain frame in a manner to enable the operator to swing the sameoutwardly parallel and in the same line with the gathering-blade toenable the operator to shirr goods or to form ruffies and gathers Withthe attachment without detaching 4the said separator.

The operation of my improved adjusting device in thecombinationdescribed is as follows: Byturning the thumb nutorscrewE inthe proper direction the cani G is forced in a direction either up ordown, thereby diminishing or increasing the space between the sidesthereof and the ends of the horns of the horizontal lever adapted tocollide therewith. In this manner the throw of 'the gatheringblade isvaried as well as the fullness of the ruiiie, gather, or shirr. One sideof the said cam extends outwardly at a different and greater angle thandoes the other, sov that the variation caused by the adjustment of thecam is greater on the retreat of the blade than the advance of the bladeto the needle, the object being to afford the proper adjustment with asingle device by which a Very percep- IOO tible variation may be securedin the retreat over thenadvance of the blade.

Having thus set forth my invention, What I claim as new, and desire tosecure by Letters Patent of the United States of America, isl. In aruftling, gathering, and shirring attachment for sewing-machines, thecombi-V nation, Vwith a supporting-frame, gatheringblade, ahorizontally-arranged actuating-lever adapted at one end for connectionwith the needle-bar of a sewing-machine and at its opposite end providedwith a fork or opening, and a vertically-*arranged lever and aconnecting-guide for supporting and operating said gathering-blade, of atapering or Wedge-shaped device adjustably secured. on said verticallever and provided With a threaded arm extending through and supportedby an arnl or flange projecting from said vertical lever and anadjusting-screw located on said threadedarm of the adjusting device tooperate the latter, in a manner substantially as and for the purpose setforth.

2. A rnftling, gathering, and shirring attachment for sewingmachines,consistingrof a supporting-frame adaptedrto be detachably heldl by thepresser-bar of a sewing-machine,ahorizontally-arrangedactuating-leveradapted at one end forconnectionlwith the needlebar andat er near itsopposite end isbifurcated, lforming an opening, a vertically-arranged lever,aconnecting-guide for supporting a gathering-blade, an adjustable hingedseparator-plate, and a tapering or Wedgej shaped adjusting device adjustably supported on said vertical lever/and Within the said opening inthe horizontal lever by pin-andslot connection in a manner to have avertical adjustment thereon and provided with a threaded stern, and anadj usting-screw located on said stem and held in avertically-stationaryposition by means of an arm or Harige of said vertical lever,substantially as and for the purpose set forth.

3. In a ruff-ling, gathering, and shirring attachment forsewing-machines, the combination, With a supporting-frame adapted forconnection With the presser-bar gathering-blade, a horizontally-arrangedactuating-lever provided With afork or opening located adjacent to itspivot-point, a vertically-arranged lever anda-` connecting-guide forsupporting and operating said gathering-blade, and a tapering orWedge-shaped adjusting device adj ustably attached to said verticallever and operating Within the forked end'of said actuating-lever forregulating `the throw of the blade and provided With a threaded stemextending through and supported by an ear or ange of the said verticallever,A of an adjusting screw or nut located on said threaded stem ata'point above the said supporting-flange, substantially as and forthepurpose set forth.
